Reverberation chamber tests object's reaction to electromagnetic fields
Use the electromagnetic compatibility (EMC) test equipment to evaluate the electrical conducted or wireless performance and integrity of any product, from automobiles to furniture
Conduct tests according to majority of standards
FORCE Technology has many test facilities and can conduct tests according to the majority of product and generic standards. In our reverberation chamber, the test object can be subjected to very high levels of electromagnetic fields.
Create a diffuse or random incidence sound field
A reverberation room is designed to create a diffuse or random incidence sound field, for instance, one with a uniform distribution of acoustic energy and random direction of sound incidence over a short period of time.
Reverberation chambers tend to be large rooms as the resulting sound field becomes more diffused with increased path length and hard exposed surfaces. The change of impedance (compared to the air) that these surfaces present to incident sound are so large that virtually all of the acoustic energy that hits a surface is reflected back into the room.
Arranging the room surfaces (including the ceiling) to be non-parallel helps inhibit the formation of standing waves. Additional acoustic diffusers are often used to create more reflecting surfaces and further encourage even distribution of any particular sound field.
Reverberation chamber relevant to acoustics and electrodynamics businesses
Reverberation chambers are used in acoustics and electrodynamics, like when measuring microphone calibration, the sound power of a source or the absorption coefficient of a material. All these techniques assume the sound field in the chamber to be diffuse and will typically use a broadband sound source like white or pink noise so that the resulting sound field contains acoustic energy across the entire audible range.
Add depth to sounds in studios
Reverberation effects are often used in studios to add depth to sounds. Reverberation changes the perceived spectral structure of a sound but does not alter the pitch.
